Dan Mathias is an American entrepreneur and roboticist who has single-handedly built a number of robots over the past few decades, including a pretty impressive full-size bipedal humanoid called ATOM-7XP. In just three months he has managed to build his own version of an edutainment robot called KATE (Kids Avatar Teacher and Entertainer). According to Dan, the idea was to build a bot that military servicemen and women could use to interact with loved ones when away from home, but could also find work as a teaching tool or entertainment robot.

"Instead of trying to produce a programme to simulate the adult mind, why not rather try to produce one which simulates the child's? If this were then subjected to an appropriate course of education one would obtain the adult brain." - Alan Turing
